Paul McCartney’s estranged wife accuses the beloved Beatle of being a violent, heartless fiend who stabbed her with a broken wine glass, beat her, choked her – and forbade her from breast-feeding their child by declaring, “They are my breasts!”

Heather Mills McCartney makes the shocking claims in the court papers she filed in her multimillion-dollar divorce from Sir Paul, according to reports in the British press.

Paul officially refused to comment on the allegations, although sources close to him told the Daily Mail of London that he was “incandescent with rage” and that he called the allegations “ludicrous.”

His former publicist Geoff Baker said, “Heather Mills is a complete fantasist, and I would not believe her if she told me the sun set in the west.”

The couple initially said their split would be amicable, but the break- up has become a torrid mess of stunning charges that the Beatle bassist turned the four-year marriage into a hard day’s nightmare.

Mills says he subjected her to a campaign of cruelty in which he:

* Used illegal drugs, drank excessively, vomited all over himself, and called her names, such as “ungrateful bitch.”

* Became “physically violent” and acted in a “vindictive, punitive manner towards her.”

* Stabbed her in the arm with a broken wine glass shortly before they split up.

* Made her put off an operation on the remains of her amputated leg because it got in the way of his vacation plans.

* Gave her a shove that sent her flying over a coffee table, and also pushed her into a bathtub while she was pregnant.

* Throttled her by the throat in an effort to terrorize her.

* Refused to let her get an antique bedpan, which would have spared her from having to hobble and crawl to the bathroom at night.

* Demanded she not breast-feed their daughter, Beatrice, because, he said, “They are my breasts.”

Mills’ lawyer, Mishcon de Reya, who represented Princess Diana in her split from Prince Charles, refused to elaborate on the claims. But an aide yesterday said that the 38-year-old former model and anti-land-mine activist “stands by everything that has been filed at court on her behalf.”

The couple’s breakup shocked the world when it was revealed in May.

They initially blamed their marital woes on the pressures of living in the limelight, and indicated they would split amicably.

But hopes of an easy divorce have been dashed as they battle over Sir Paul’s estimated $1.5 billion fortune.

The couple has no prenuptial agreement, and British legal experts estimate the singer could lose up to a quarter of his assets.

According to The Sun newspaper in England, Mills’ court papers also detail an alleged violent outburst about a month before they split.

She claims that in April, Paul spilled red wine over her during one episode – then reached out to grab the glass, snapping it off at the stem in the process.

“He lunged at the respondent with the broken sharp stem of the wine glass, which cut and pierced the respondent’s arm just below the elbow, and it began to bleed profusely,” The Sun quoted the court papers as saying.

According to the Daily Mail, McCartney then allegedly “flung her into her wheelchair and wheeled it outside, screaming at her to apologize for ‘winding him up.’ ”

She reportedly claims she still bears the scars of the attack.

Although the 64-year-old McCartney has a reputation of one of the gentlest and most easy-going rock stars around, Mills claims the glass incident was far from the only instance of brutality.

She says that while they were in Los Angeles in November 2002, he “grabbed her by the neck and pushed her over a coffee table,” according to The Sun said. He then stormed outside, fell down and cut his arm, she claimed.

Then, in May 2003, he shoved her into a bathtub while she was four weeks pregnant with their daughter, she claimed.

After the birth, Mills said she gave up breast-feeding baby Beatrice because McCartney allegedly told her, “I don’t want a mouthful of breast milk,” according to the Daily Mail.

In August 2003, according to the paper, Sir Paul had another violent outburst, this time on Long Island.

Mills claims that she confronted him about his alleged marijuana smoking and he blew his top. Becoming “very angry, [he] yelled at her, grabbed her neck and started choking her,” according to the Daily Mail.

In addition to the drugs, she claimed he would sometimes go on epic drinking binges. Once, “She found him lying naked and semiconscious in the bath covered with vomit,” the Daily Mail said.

While some suspect the court papers were leaked by Mills’ p.r. gurus, her spokesman, Phil Hall, said she was shocked to learn the secret alle- gations were published in the London press.

“She has kept a dignified silence. She has not spoken about anything, and that is still her view. She won’t speak about anything,” he told ITV1’s “This Morning” show.

While McCartney would not address the charges, the law firm representing him released a statement saying, “Our client would very much like to respond in public and in detail to the allegations . . . but he recognizes, on advice, that the only correct forum for his response to the allegations made against him is in the current divorce proceedings.

“Our client will be defending these allegations vigorously and appropriately. Our client is saddened by the breakdown of his marriage, and requests that his family is allowed to conduct their personal affairs out of the media spotlight for the sake of everybody involved.”

The couple had been battling in the London press all summer for the media high ground, with Mills taking a savage beating as embarrassing nude photos surfaced.

Some observers of the couple think that Mills, who lost her leg in a 1993 motorcycle wreck, is now trying to turn the tables and get some public sympathy.

One pal told the Daily Mail that she and her handlers appear to be “orchestrating the leak to maximize sympathy for her.”

But the source added, “This is coming from a woman with a well-documented problem with the truth. This document was leaked with the specific intention in mind of damaging Paul’s reputation and trying to hurt Paul.”
